My site won't go down, if it did I can always move the site to a dedicated VPS. So far that has never been required for the last few years. The only reason I do not post pdf's is I do adjust the instructions from time to time as I get more info, reports any issues, or fix typos, etc.

I have the euro switch, but that DIY couldn't be simpler. Are older switches the same? Can't figure out what lego pieces were for, but never read those DIY instructions to be honest, since I wanted a factory look .
